D0150 Dental Code - Comprehensive Oral Evaluation - New or Established Patient

D0150 Dental Code: A Guide to What Comprehensive Oral Evaluation Entails

Dental code d0150 description: Comprehensive oral examination

Procedure code D0150 applies to various patient scenarios, including new patients, established patients with notable changes in their health conditions or encountering unusual circumstances (as reported), and established patients who have been absent from active treatment for three or more years.


  1. It is necessary for proper diagnosis and treatment plans; for instance, after conducting a comprehensive oral evaluation (D0150), a dentist may identify specific teeth at risk of developing dental cavities or caries. In such cases, the dental practitioners may suggest dental sealants (D1351) as a preventive measure.
  2. Most importantly, it is necessary to gain proper reimbursement for services provided by dentists.

What Does D0150 Comprehensive Oral Evaluation Include?

D0150 dental procedure includes a comprehensive examination and documentation of the oral cavity's external and internal structures and surrounding tissues at a 360-degree angle. The assessment encompasses several critical components, beginning with a meticulous evaluation of signs of oral cancer. It also includes a thorough review and capturing of the patient's dental and medical history and a comprehensive assessment of their overall health status. This comprehensive evaluation may encompass various aspects such as examining and documenting dental caries, identifying missing or unerupted teeth, assessing existing dental restorations, and evaluating prosthetic devices in place. Furthermore, the procedure involves the assessment of occlusal relationships, which relate to how the teeth come together when the patient bites or chews. It also encompasses a detailed evaluation of the patient's periodontal condition to determine the health of the gums and supporting structures surrounding the teeth. Lastly, this comprehensive examination includes identifying and documenting any anomalies or abnormalities in the oral cavity's hard and soft tissues.

Billing Frequency for D0150 Procedure

The frequency at which code D0150 can be billed depends on the specific guidelines and policies of the dental insurance or third-party payer. D0150, which represents a comprehensive oral evaluation for an established patient, is subject to particular limitations set by the insurance company or payer.
Dental insurance plans may commonly allow D0150 to be billed once in a specific period, such as once every six months or once per calendar year. Sometimes, payment plans may allow up to two comprehensive oral evaluations per year. However, these limitations can vary widely between different insurance plans, so it is crucial to check with the specific insurance provider or payer for their coverage policies and limitations regarding the frequency of billing for D0150.

D0150 Code Myths and Realities

There is often some misunderstanding surrounding the D0150 dental code. Some individuals mistakenly assume that this code can only be utilized when treating new patients. This misconception likely stems from the fact that many dental insurance plans impose a "once per lifetime" restriction on this code. While it is true that many insurance plans primarily reimburse D0150 for new patients, it is essential to note that this code can also be appropriately used in cases where established patients experience a significant change in their health status or encounter other exceptional circumstances. So, dental professionals must understand the versatile application of this code beyond just new patient scenarios, taking into account these various circumstances and ensuring accurate documentation.

Difference between d0150 and d0180

D0150 and D0180 pertain to Comprehensive Oral Evaluations for patients, whether new or established. The primary difference between the two lies in the clinical context and the extent of periodontal assessment involved.

D0150 D0180
It includes an overall assessment of the patient's oral health, encompassing a periodontal screening and noting any soft tissue anomalies. D0180 is reserved explicitly for patients exhibiting signs or symptoms of periodontal disease or having risk factors like smoking or diabetes. It involves a comprehensive periodontal assessment.
D0150 does not always require comprehensive periodontal charting, which involves a detailed evaluation of parameters such as probing depth, bleeding points, mobility, recession, attachment loss, furcations, and a formal periodontal diagnosis. D0180 mandates complete periodontal charting, including, but not limited to, evaluating six specific points around each tooth, probing depth measurement, measuring attachment loss, assessing tooth mobility, recording recession, identifying bleeding points, furcation assessment, and establishing a formal periodontal diagnosis.

Proper Application of CDT Code D0150: Clarifying Usage Guidelines

  1. As discussed earlier, contrary to a common misconception, CDT code D0150 is not exclusively for new patients.
  2. While D0150 covers the comprehensive evaluation, any additional diagnostic procedures performed beyond the standard evaluation should be reported separately using the appropriate CDT codes.
  3. Suppose you have submitted a claim with the code D0150 for an established patient, and the claim is denied because it exceeds the allowable frequency for that code. In that case, you should request an alternative benefit using code D0120.
  4. In cases of unusual circumstances not covered by standard guidelines, D0150 may still be used. However, dental professionals must provide detailed documentation ("by report") explaining why this code is appropriate in the given situation.
  5. If applicable, verify the patient's insurance coverage and ensure that the patient's insurance plan supports CDT code D0150. Some insurance plans may have specific guidelines or requirements for using this code.
